ons -that the removal ofv the sheet of paper '95 bythe block; Fig, 2 isrearperspveetire View g4 and Fig. 3 is a longitudinalsec'tion.'Corresponding andv like 'parts are referred, to in the followingdescription and indicated I ,in all the views of the A' saniereferen'cecharacters. I My improved iiy catcher consists,fessen. tially, of a traythat serves as a fly pape-r' holder. The tray has a bottom orhaseplatevl which is substantially flat, although .not 65 necessarily so, thebottom being oany suitable size or shape and being shown in the presentinstance as of'rectangular form. The bottom is provided a't allv of itsedges with an upturned 4rini 2` The entire tray is 70 preferably formed`from a single .piece of suitable sheet metal, the edge :portions otVwhich are bent upwardly to form therini.- A sheet of sticky paper B'litssnugly with- Y in the rim and lies Hat' against the` bottom .1.7.5

with itsV adhesive side exposed. In order to maintain the paper inplace, a plurality of lugs 4 project i are arranged in spaced engageover the edge portions4 of the sheet of paper, as shown. The sheet ofpaper extends across and 'closes a relatively large opening 5 that isformed in the bottom of the tray.- The purpose of this opening is to 35`permit the finger to be inserted therethrough away from the to pressthe sheet of paper bottom 'l and out of engagement with theinwardlyprojecting lugs 4. A niaterial advantage 1s attained with thisarrangement 99 inasmuch as the sheet of paper is rendered susceptible ofbeiiig expeditiously removed from the tray to be 4replaced by 'anew,sheet It 'i v il1., be .obvi

may be effected withoutthe finger of the operator coming into contactWith the adhesive surface'.

The tray may be moved about by means ot a hantlle 6 which 'is preferablyformed of a 10b single length of stout wire that is doubled 'upon itselfat anintermediate point to form spring arms 7.' Thea-rms are crossedintermediate of theirends and have inwardly bent extremities 8- that areaction of the arms, in A transversely spaced apertures 9 extendingthrough the bottom Inasln'uch as --the arms are crossed, there is atendenc for the engagement with free ends thereof to spring toget er,and 11 inwardly from the rim at suitable intervals and relation to thebottoni of the tray so as -to held by the spring this, of course,insures`the bent extremities- '9 being firmly' retained at all times inengageinentwith the a 'ertures, although admittil o f-the handle eingreadily detached froml t e tray by merely pressing the arms apart. Oneof tV e spring arms is somewhat longer ythan the other and the apertures9. are spaced eplart -in the direction 'of the length of the andle inorder to compensate' for thisdift'er'ence in the length of the arms. Byvirture' of this construction, the handle is held against turningmovement about the bent extremities -9 as pivots andl is maintained.rigidl in oblique relation to the plane of the ottoni of the tray, thehandle,

projecting ,considerably beyond one end of `the tray so as to beconveniently grasped when using the device., A.

' In practice, `the catcher may be moved rapidly about to cause theflies vto'strike against and be retained by the adhesive'surface of; thesheet of paper 3. The tray may also be placed over a fly or flies whichhave `vlighted on a vvall'or like Hat object, the flies being caught vbythe sticky 'paper as they at-v tempttoescape. -In this instance theupstanding rim 2 'prevents the adhesive sur- Y `faceof the'paper fromcoming into Contact with the wall.

v Attentionjis particularly directed. to the fact that the vlugs 4 are'struck from the metal forming the rim. Outlet openings 10 are thusprovided in the rim` and permit the air to escape from the tray .as thedevice is moved about, so as'not'to hinder such move'- ment. l The freepassage of air through the tray avoids the formation of an air cushion'asaivould possiblypermit theinsects'- to escape. i From 'theforegoing'4 description 'in ccnl. nection Withthe' accompanyingd'rawing, it

-.Will be ap arent that II' have-provided an' l improved '.f yucatch'erwhich' is quite efficient 'in operation,` which is not likely to' getout of: order, andwhicli possesses to marked degree the characteristicsof simplicity, dus' rability and stren th., The (levi-ce consists ofcoin'paratively parts that are capable of: leing easily and cheaplymanufactured so as to-perinit .the invention to be,placedcnv the-marketat a price not toogreat to. 'pre "vent its general adoption.' I

.It is to be vui'iderst'oo'd,that the-'device ma made in 'various''sizes-'it bei-ng "tonteml.

lated to equip the larger sizes with long,

handles to permit their use in capturing iiies on the ceilin 'of rooms.

AWhere it is not desired to move the de- Y. j vlce about to catchtheflies, the saine may be supported in a stationary position in anysuitable manner, as by means of a block-11 that is adapted to rest uponatable or like support and is formed with a slot 12 -into whichthereturnedend-'of the handle may be iitted frictionally, as illustratedin Fig. 1.

The handle may be disposed at a greater angle tothe tra than in Figsaland 2, as

for instance, asi lustrate'dV in Fig'. 3. 1 Having thus described :theinvention, what is claimed as new is:

l'` A iy catcher including a plate, ai`inarginal rim outstanding fromoneside ofthe plate, and a plurality of lugs projecting in#- Wardly. fromthe rim and arranged to en gage over a sheet of sticky paper to hold thesame against the plate, the lugs being struck from the rim to provideair outlet openings therein for the purpose specified.

2. As a new article of manufacture, al'Hy catcher comprising a handle,and a tray se' cured to the handle and consisting of a bottoni, anupstanding rim, and a plurality'of "lugs projecting .inwardly from therii'n and the other topi-event the handle from turn- -ing relative'to'the tray.

v 4.. As a new article of manufacture, av fly catcher comprisinga tray-for holding a-.sheet oflsticlcy paper, and a handle :including a pairof spring arms connected' together at one eiid'and crossed intermediateof their ends, withv their free terminals engaged with the tray. A
